IMPROVEMENT IN HVDROCARBON -BURNERS AND GAS-GENERATORS.

Specification forming part of Letters Patent No. 17 [,278, datedDecember 21, 1875 application filed November 9, 1575.

To all whom it may concern Be it known that I, ALVAH J. GRIFFIN, ofLowell, of the county of Middlesex and State of Massachusetts, haveinvented a new and useful Improvement in Hydrocarbon- Burners andGas-Generators; and do hereby declare the same to be fully describedinthe following specification and represented in the accompanyingdrawings, of which Figure 1' is a top view, Fig. 2 a side elevation, andFig. 3 a bottom view, of my improved apparatus. Fig. 4 is a horizontalsection of it.

My present invention is an improvement with reference to thoseheretofore patented by me, and described in my United States Patents No.56,143, of July 3, 1866, and No. 63,881, of April 16, 1867.

In my present apparatus each of the longitudinal chambers of the heaterhas in it a series of partitions, by which a tortuous current iseffected in the fluid or matter which may pass through it, such servingto heat such fluid or matter to better advantage than heretofore.Mypresent invention, however, relates more particularly to thearrangement of the eduction-pipes with respect' to the heater, wherebythey become exposed to the blaze and heat of the burner, and, as aconsequence, not only is the water vaporized to better advantage, andthe steam superheated, but the petroleum and the fluid to be con vertedinto gas are also better heated and vaporized. Furthermore, otherbeneficial results follow from the improvement.

In the drawings, A denotes a hollow vessel,

. heater, or retort, divided lengthwise by two partitions, a. 1), intothree chambers, in each of which is a series of transverse partitions,b 1) b which are arranged as shown. Each of them projects from one sideof the chamber, and terminates near the opposite side thereof, eachpartition being extended from that side which is opposite to that fromwhich the next one projects, the series causing the fluid or water inpassing through the chamber to have a sinuous current, whereby itbecomes heated to better advantage. Conduits E F G lead into thesechambers at one end of the retort. Other pipes, H I K, also lead out ofthem at the opposite end of such retort. The pipe H extends aroundoutside of the entire retort, and thence descends and passes aroundunderneath it, and is closed at its lower eiid. Furthermore such pipe,where below the retort, is foraminous on its upper surface, or puncturedwith a series of holes for steam to be discharged from it when theapparatus is in operation. The pipe I simply descends and passesunderneath the retort, and terminates in a jet, d, placed directly under'the center of the retort. The pipe K, leading out of the chamber D,passes entirely around the retort, or about its sides and ends, inmanner as shown. This pipe is to take from the chamber D the vapor andgas produced therein.

When the apparatus is in use water enters the chamber B by the induct E,and in passing through such chamber becomes highly heated and convertedinto steam, which flows through the pipe H, and becoming superheated insuch will be discharged beneath the retort into the flame of the burneror gas-jet. Petroleum also is passed into the chamber 0 by the pipe F,and, being heated and vaporized, escapes from the chamber through thepipe I and its jet, upon which it is enflamed.

The chamber D receives from the induct G the hydrocarbon fluid intendedto be resolved into gas. In passing through the said chamber Dand thepipe K the conversion of the fluid into gas is very thoroughly accomplished, particularly by the educt K, heated by exposure to the flame ofthe burner, which spreads laterally in all directions under the retortwith great power and effect.

1 claim as my invention in the said gas apparatus as follows l. Theretort having the transverse partitions b b b of its chambers arrangedrelatively to the longitudinal partitions a b, as described andrepresented.

2. In combination with the retort, the steam and gas pipes Hand I,arranged to discharge beneath it, as described, each pipe HK coiledaround the sides and ends of the retort, substantially as shown, so asto be exposed to the flame of the combined jets -of steam and vaporizedpetroleum, as explained, when the apparatus may be in operation.
